shared/051 fails on CRC enabled filesystems because it doesn't get
an erro on setting the 26th ACL on a file. CRC enabled filesystems
support more than 25, so there shoul dbe no error.

Allow the test to pass on both non-CRC and CRC enabled filesystems
by detecting the type of filesystem configuration and using that
information to fake the error message so that the golden output
match does not fail. We also need to filter the 26th ACL from the
output otherwise that will cause failures, too.
